STUMP-BURNER.

, Specification of Letters Patent.

Application:filedNovember 19,1918. Seria1No.263,162. 3

To all whom it may concern:

Be it knownthat-I,ELLswoRTn TILDEN,

a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Stump-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of. reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for burning stumps and consists essentially in the provision of a means for burning the roots without injuring the body portion of the stump, which may be used for fuel or other purposes.

The present invention consists of a simple and eflicient device of this, nature having various details of construction, combination and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings which, with the numerals of reference marked thereon, form a part of this application and in which:

Figure 1 is a vertical central sectional view through a stump and the apparatus for burning the same.

Fig. 2 is a top plan view.

Fig. 3 is a detail view of a hood, and

Fig. 4: is a sectional view showing a modified means of burning the stump.

Reference now being had to the details of the drawings by numerals;

1 designates a stump and 2 the ground in which the same is rooted, and which ground is recessed away as at 3 forming a hole in which the firemay be started. The ground is also recessed away as at 1 diametrically opposite the hole 3 in which the fire is kindled, and an opening 5 is formed through the tap root, or other roots of the stump, forming a flue through which the smoke and fire from the hole 3 passes. A metallic hood 6, a detail of which is shown in Fig. 3 of the drawings, has one end 7 concaved, designed to conform to the contour of the stump against which it is adapted to contact and its other end rests upon the bottom of the hole 4, as shown in Fig. 1 of the drawings. Said hood is apertured as at ,8 for the reception of a pipe 9 having an elbow 10 at its lower end, and which affords means for creating a draft through the opening in the stump from the hole 3. After 'the hood is adjusted in place a covering of earth 11 is placed over the same, covering the entire surface of the hood and which reaches an air chamber underneath the hood. In Fig. t of the drawings is shown a slight modification of my means for burning stumps and in which the hole 12 is formed in the ground at one side of the stump, and another hole 13 opposite, and in which a draft pipe lt is placed which, after being adjusted in place, is covered up with earth, a hole or passageway 15 being made between the roots, forming a means of communication betweenthe fire hole 12 and the hole in which the draft pipe is positioned.

In operation, referring to Fig. 1 of the drawings, fire is started in the fire hole 3 and the draft from the pipe will cause the flame to be drawn through the opening 5, first drying out the roots, the hot air accumulating in the air chamber at the inlet to the elbow end of the draft pipe and tend to further dry out the roots before they are burned. By the provision of the air chamber, a considerable surface is exposed to the roots, in order to thoroughly dry the same before being consumed. The fire is continued in the hole until the roots are thoroughly dried and seasoned and fire started well among the roots, after which they will burn without further attention. After the roots have been thoroughly burned the stump may be toppled over and used for fuel or other purposes.

In the modified form shown in Fig. 4: of the drawings, the hole is made between the roots, rather than through the tap root, as in Fig. 1, the burning being confined to the roots without injury to the wooden structure above, making the stump available for fuel or other purposes.

What I claim to be new is:

An apparatus for burning stumps, comprising a metallic hood concaved at one end and adapted to be positioned at an inclination in an excavation in the ground with its upper end concaved, and designed to engage the convex surface of a stump to be burned, the lower portion of the hood having an opening, an elbow having an upright Patented July 2 2, 1919.
